Nanopower™ load switches are tiny, fast, ultra-efficient, with near
zero power consumption offered in TDFN packages based on Silego’s CuFET™
technology

SANTA CLARA, Calif. — (BUSINESS WIRE) — October 15, 2013 —
Silego Technology’s Power Division introduces the Nanopower load switch
family. The Nanopower family launches with two products: the SLG59M1470V
supporting up to 6 A loads and the SLG59M1460V supporting up to 2 A
loads. Silego’s proprietary sub-micron copper power FET technology
supports the world’s smallest full-featured, high efficiency power
switches down to 1 x 1 mm in standard plastic packaging.

Nanopower load switches support very fast power rail switching down to
9.5 μs. This fast switch-on characteristic allows any sub-system to be
powered quickly while providing power isolation when off. When enabled
the SLG59M1470V only consumes 35 nA in active mode. The ultra-low power
consumption during sleep mode and low Rds(ON) performance during active
mode significantly increases battery life.

“Mobile system designers desire load switches that achieve three
parameters at the same time: fast turn on, low Rds(ON), and low power
consumption. Existing P-Channel MOSFET solutions achieve decent turn on
speed with low power consumption, but suffer high Rds(ON) when the power
rail is below 2.5 V,” said Jay Li, Director of Marketing. “Our Nanopower
devices are the world’s first integrated load switches that achieve all
three key mobile performance parameters. This device is widely adopted
on many next generation mobile devices including tablets, notebooks, and
smartphones.”

SLG59M1470V is packaged in a 9 pin, 1.5 x 2.0 mm STDFN package. The
device can switch power rails down to 1.0 V. The Rds(ON) of the
SLG59M1470V is rated at 7.4 mΩ.

SLG59M1460V is packaged in an 8 pin, 1.0 x 1.6 mm STDFN package. The
device can switch power rails down to 1.0 V. The Rds(ON) of the
SLG59M1460V is rated at 21.3 mΩ.
